n l um vrou 145 pipe Patented May 26, 1931 UNITED STATES LEWIS J. THOMAS AND AUBE-EY RIDDLE, OF EKRON, KENTUCKY SMOKING PIPE Application led April 24,

This invention relates vtosmoking appliances and more particularly to a pipe `by means of which tobacco is smoked.

When a tobacco pipe has been used for some time the smoke passage through its stem and mouth piece often becomes clogged by nicotine and, also, it often happens that saliva will pass through the smoke passage and cause the bowl in which tobacco is packed l to become soggy. Therefore, one object of the invention is to provide a pipe which will not be liable to become clogged and which will not be liable to become soggy and strong by saliva working into the tobacco receiving chamber of the bowl.

Another object of the invention is to cause saliva which may work through the mouth piece of the pipe to be led through a separate passage in the stem of the pipe and delivered into a sub-chamber formed in the bowl beneath the tobacco receiving chamber where the saliva and nicotine will be subjected to heat so` that the nicotine will be dried and the saliva converted into steam which passes from the sub-chamber through an opening or outlet.

Another objectV of the invention is to permit a false bottom which divides the bowl of the pipe into-a tobacco receiving chamber and sub-chamber7 to be'removed, thereby permitting access to the sub-chamber so that it may be thoroughly cleaned when necessary. i f

Another object of the invention is to provide a pipe in which the mouth piece will be firmly but releasably held in engagement with the stem of the pipe by tubes constituting liners for the smoke passage and saliva passage.

The invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a longitudinal sectional view through the improved pipe.

Figure 2 is a View showing the improved principally in top plan and partially in section. Y

Fgure 3 is artransverse sectional view taken on the line 3 3 of Figure 1.

rlhis improved pipe includes a bowl 1 from x which extendsa stemQ and a mouth piece 3 192s. semi No. 357,811.

which may be formed of any material desired and is disposed in abuttingend to end relation to the stem. A ferrule 41 of metal is provided about the outer end portion of the stem to reinforce it but the' ferrule may be omitted if so desired. v

In order to divide the bowl into a main tobacco receiving chamber 5 and sub-chamber 6, there has been provided av false bottom 7. consisting of a metal disc which lits snugly within the bowl 'and rests upon an annular shoulder 8 formed in spaced relation to the lower end of the bowl. An opening 9 is formed centrally through the disc 7 andY through this opening is passed a screwY 10 which engages in the bottom of the bowl, as shown in Figure 1, `and securely but releasably holds the false bottom in place. Therefore, the false bottom may be removed in or-. der to permit access to the sub-chamber when it is necessary to clean the same. In view of the fact that the false bottom is-formed of metal it will become highly heated when the pipe is in use and this heatwill causesaliva which accumulates in the sub-chamber to be 75 converted into steam. An outlet passage 11 for the steam leads from the sub-Chamberland upwardly through the wall of the bowl. A liner 12consisting of a metal tube is provided for the steam passage 11 and in order to reinforce the bowl about the upper end ofthe steam passage, ythere has been providedy a guard consisting of a strip of sheet metal 13 which is secured byfasteners 14 driveninto the wall of the bowl and formed with an opening 15 registering with the steam passa e.

smoke passage 16 is formed longitudinally through the stem with its forward end communicating with the tobacco chamber 90 above the false bottom 7 and vbeneath this smoke passage is formed a saliva passage 17 leading from the sub-chamber' for the full length ofthe stem and having communication with the smoke passagethrough a passage` 18 95 n formed vertically in the i bowl in slightly spaced relation to the outer or rear end of the stem. By this arrangement, saliva may be led from the smoke passage into :the saliva passage' through which Yit will ypass until it' 100 rea-ches the saliva chamber. Nicotine will be carried through the saliva passage with the saliva and the heat radiating from the false bottom will cause the saliva to be changed into steam and the nicotine to be dried. A liner consisting of a tube 19 has been provided for the saliva passage and the smoke passage is lined by a similar'tubc 20, and from an inspection of Figures l and 3, it willbe seen that these tubes are formed with side openings 2l and 22 disposed in'opposed relation to each other and adapted to register with the passage 18. The tube 20 also constitutes a liner-forthe smoke passage 23 formed through the mouth piece 3 and fits tightlyinthe passage 23 so that when the mouth piece is drawn away from the stem invorder to 'detach it, the tube20y will be vwithdrawn from the smokepassage'l.

20y l'sali'va'bein'g forced from the tube into the bot- By this arrangement the tube QO'may be thoroughly cleaned vwithout danger-of nicotine or tomof the tobacco chamber. The tube 19 fits tightly in the saliva passage 1.7 andis of such length that its rear end projects from the stem and lits into a socket 24- formed in the mouth piece below the smoke passage 23. Therefore, the stem will be firmly heldin engagementwith'the mouth piece and as air is sucked `through the'tube 2() when the/pipe :is in use, a very Vgood draftwvill be provided.

`Inorder to prevent danger of the tube being bent therehas been providedpins which are 'threaded into the stem at oppositesides of the smoke passage andproject from the stem for engagement inrv sockets 26 formed in the mouth piece.

Vhen this improved smoking pipe is (in use, tobacco is packed into the bowl Vin the usual manner and smokeand air drawn from Vthe'bowlthrough the 'tube 20. Any nicotine or saliva which accumulates in -the tube Q0 passes through the passagel'S'into the tube .19 andflows forwardly through this-tube into 'the sub-chamber 6 where heat radiated from the 'false bottom will cause the saliva to be 'converted into steam and the nicotine to Abe dried.y rl`he steam Apasses out through the steam passa ge.V It will thusbe secni that saliva and nicotine will bepr-evented from accumulating in the bottom of thetobacco chamber andthe pipe will beprevented from becoming soggy and strong., 'If the tubefQO becomes-clogged the mouth piece is with- ;drlawn from the `stem and carries with it the entire `smoke tube while the saliva tube will piece .again assembled. If it is `foundnecessary to also clean the saliva tubeV the false bottom can be A-removed aftenthe screw f10 has been iunscrewed and a `pipe cleaner also .passed `through the saliva tube. yThe subchamber canT be thoroughly cleanedin ,order v-to iremove `dried nicotine and the false "Nhat'is claimed is:
